微型分光光度计的研制及其在水质检测中的应用
Development of a Micro-Spectrophotometer and Its Application in Water Quality Testing
摘要
Abstract
Traditional spectrophotometers have a large volume and slow scanning speed,which limits their applicability for rapid on-site detection.Herein,a micro-spectrophotometer(named ATOM)is fabricated,and its performance is verified in water quality testing.An M-type Czerny-Turner light path structure,a broadband light emitting diode(LED)light source,and a linear charge-coupled device(CCD)photodetector were adopted in ATOM.The performance of ATOM was validated through iron content determination by using o-phenanthroline spectrophotometry.The experiment results showed that the linear correlation coefficient of determination R2 was 0.9997 for mass concentrations ranging from 0 to 2.0 μg/mL.The relative standard deviation was 0.37％,and the relative error compared to a commercial large-scale spectrophotometer was below 1.4％.The dimensions of ATOM are 75 mm × 60 mm × 25 mm,with hardware costs of approximately 1 000 CNY.ATOM features compact size,low cost,rapid measurement,high integration and high precision,making it suitable for portable on-site rapid detection.关键词
